7.2  Font editor

The font editor allow you to modify the appearance of characters as
they are displayed on the screen. The font editor handles both 40-
column and 80-column fonts. When you run the font editor, it
initially displays the default 40-column font, which is copied from the
Commodore 64's character ROM. You can switch between 40-
column and 80-column mode by pressing the X key.

Loading a font and editing characters involves the same key
commands in either mode. To load a font into memory, press the L
key and supply the name of a font file.

Use the cursor keys to select a character to edit. The character number
is displayed, and a blown-up version of the character is shown for
editing. To edit the character, press RETURN. In edit mode, use the
cursor keys to move the asterisk, and use the SPACE key to turn a
pixel on or off. As you modify the character, you'll see the change
take effect in the actual-sized character. Press RETURN again when
you are finished editing. When you are finished editing the font, press
S to save it.

The 40-column font editor has  number of extra commands that are
useful for manipulating characters:

Reverse:  Invert every pixel in the current character.
Flip:  Do a vertical flip of the character.
Mirror:  Do a horizontal flip of the character.
Rotate:  Rotate the character 90 degrees clockwise.
Upspin:  Shift the character up one pixel.
Downspin:  Shift the character down one pixel.
Leftspin:  Shift the character left one pixel.
Rightspin:  Shift the character right one pixel.
Fill buffer:  Copy the current character into the buffer space.
Write buffer:  Copy the pattern in the buffer to the current character.
Copy chars to reverse:  Copy the first half of the character set to the
second half, reversing each character at the same time.

The configuration program is started automatically if you try to run
Novaterm without a configuration file. It can also be used at any time
to reset the configuration to a new state. See section 1.1, Starting up
the program for a description of the options in the configuration
program.
